I loved Robin Williams comedy routine when he talks about Wild Kingdom in a Marlon Perkins voice: “My assistant Jim will attempt to circumcise a water buffalo.” and Jim is going “Oh s**t, oh s**t” and the Water Buffalo says “Clown, the only thing between you and me is that tranquilizer s**t!”
How about this one, which, though the topic is Intelligent Design, has a lot of good information about the earth in it:
Privileged Species featuring Dr. Michael Denton (it starts off with a clip from “the science guy”, but don’t be fooled, stick with it).
